How can this driver even see the road with sunshade covering his windscreen?

We don't know what this sorcery is, or how this van driver is able to drive with the sunshade seemingly blocking his entire windscreen.

Stomper Justy shared with us this unusual sight taken from his car's rear camera. 

According to him, he spotted the van along Buangkok East Drive towards Sengkang East Driver junction today (JUne 5) at about 3.46pm.

"While driving on the expressway, spotted this van.

"Wow! Can drive with sunshade on. Hmm... wonder how he drive!"

Anyone has any ideas?
